Thanks in advanced. I am working with an Avaya G3siv11. Our site is looking for a basic analog speaker phone with an LED message light that will work with their existing TN793B, TN793CP, TN746B, TN746, and TN742 analog circuit boards. I was looking at the Aastra 9110 analog phone but couldn't find any info if it would work on these circuit paks or had an LED message light. Can anyone help or suggest a phone to purchase?
